Hot Deployment in Websphere Advanced Edition version 4.0

Hi,
My application comprises of jsps , servlets and jar files. The Jsps will invoke a servlet and the servlet will talk to the jar files and return to the JSP page.
The problem Iam facing is regarding the hot deployment.I will be exporting the jar files to the lib folder of my deployment directory. Whenever I export the jar files Iam forced to stop and restart the server. Otherwise Iam getting a java.lang.ClassNotFoundException.
Earlier I was working with the websphere 3.5 standard edition. That time without stopping and restarting the server things were working properly. Does this mean websphere version 4.0 doesn't take hot deployment.
Please tell me what am I supposed do?? Am I missing something.
Thanks and Regards,

Look into your web application deployment descriptor IBM extension part, you have to turn on autoreload there. The default setting turns it off, you must specify a reloadinterval also.

Hi,
As far as I remember the hot deployment is fine for development environments but not for production as it is fairly resource intensive.
It sounds like you are using it for development though.
Thanks,
Steve
